Use it I've seen more than PHP shell being thwarted by a simple "nope, that process can't access anything but the folders it was meant to access" that SELinux offers. Run your webserver in a container, separate from the database, with read-only access to your served content/scripts SELinux today makes a lot of things easier to set up more securely. But at that point, other CMSes become far more comfortable to use. Or only run it locally on your computer to generate static sites and upload these.
So, in all brutal honesty that I can bring in the face of someone who probably "just wants to run a website":ĭump Wordpress. Your system was insecure, and I'll be honest: it all probably starts with running WordPress with random plugins. Bring up new, minimal, system.Īll this points to it really not being worth the time figuring out the security hole. Save a snapshot for later investigation / proof of innocence. In any case, it indicates the takeover didn't just happen to mine some cryptocoin, so it's likely the original attacker had a different risk of detection / profit tradeoff in mind. The change in Google search console might point to a rather benign (planned?) usage in a scheme where your site was to be modified to generate illicit ad revenue, or just as forwarder to a different site. You say you notice change in database and host disk usage, and the best explanations of that could be somewhere between abusing your system as an ad-serving bot, command and control backup of some botnet, and distribution of child porn. At this point, your server is not your own. If your system is still running: Stop it. So you have basically an unrestricted compromise of your system, and that includes all user data, database passwords, API keys …īoy, you have some passwords to change. Hacker could access root folder of my host, create files and change permission of file to allow them to be executed. So, is there a way to prevent the browser from URL-encoding the form values, while keeping the content-type to application/x-www-form-urlencoded? It has to be a POST request with the data in the body, if I use a GET request the application ignores GET parameters.I can prevent URL-encoding by changing the form encoding to text/plain but the application does not accept that encoding and returns an empty page.This breaks the payload and the XSS doesn't work. By default, the values are automatically URL encoded by the browser.
I'm trying to create a PoC for this issue by creating a custom HTML page with a hidden form pointing at the vulnerable page that will automatically submit, however, I'm running into the following issues: Burp Suite) and change my request POST body from: param1=val1¶m2=val2¶m3=val3 There is an HTML form that is submitted to this page (POST method) and sent parameters are reflected (without encoding) in the response. During an engagement, I found a potential XSS vulnerability on a page.
